Foto Service Studio Photo. Fotografia antigua construccion de barcos. S.S. Faith, barco en hormigón armado

Esta foto pertenece a un álbum donde se recoge el proceso completo de construcción del primer barco de hormigón armado de Estados Unidos, el S.S. Faith.

En este caso vemos al ingeniero Nicholson en la cubierta, a medio construir del barco. Las fotos fueron hechas por Service Studio Foto 123 Market St y son de gran calidad artística.

Curiosamente este álbum fue comprado en Estados Unidos.

Los barcos de ferro-concrete (hormigón armado) pertenecen a la historia de la marina y tuvieron un cierto auge a finales del siglo XIX y principios del XX
